To all whom t may concern.'

Be -it known that I, NELsoN B. HENRY, a

, Citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful lmprovernents in Cages for Oil-Presses, of which the following is a specification.

My invention is an improvement in cages for oil presses.

The present invention contemplates a construction of cage wherein a sleeve or tube preferably of Steel and preferably of circular outline, is filled with one or more metallic rings having 'external peripheries tightly itting the interior of the tube or sleeve and having an internal chamber to receive the cooked meats from which the oil is to be expressed. p

The ring or rings are provided with means for receiving, and conducting away, the oilv as it is expressed from the cake. The means provided are Substantially as follows:

On all sides near the internal perimeter of each of the rings, a series of openings aie drilled extending through the ring from face to face, to constitute oil ducts for leading the oil through the ring yor rings. The interior of the ring is slotted along the internal perimeter, yopposite each such opening' and lengthwise thereof, to constitute passages from the interior of the ring to the ducts or openings through the ring. ,e

In the preferred construction` after the ducts and slots are `formed,feach duct is broached to diminish the length of its slotted connection'with the interior of the ring. The edges of'the slots are also rolled `down er swaged or distorted along the interior perimeter of the ring So as toclose down or narrow theslot at its opening into the central space of the ring and'to thereby diminish the opening to minute dimensions.y

rlhe openings or ducts in the ring are relatively large-sufficiently sorto prevent clog- K ging of the holes when the oil v`is passing through the saine. The slots conducting oil fromk the cake to the ducts have a minute opening expanding as each passes toa duct, thus permitting the oil from the cakes to enter the slots in thin films but, excluding the thicker solid materials of the cakes.

While it is possiblek to form a cage with but one ring of sufficient depth to receive a plurality of cakes, it is preferable in practice to build up the cage of a plurality of rings inserted into a tube or Sleeve and with their ducts in alinement. f y

The continuous ducts thus formed by alined openings of superposed rings may be readily cleaned should matter 'accumulate therein. The formation of the conducting slots or channels opening into said ducts per mits of oil in film form passing from the interior of the ring through said slots to the ducts. The slots are minute both in width and in length'and they expand in width as they empty into said ducts. This prevents clogging of the slots.

''he nature and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, in which- Figure. l is ra horizontal sectional view illustrating and y Figs. 2, 3 and 4 are detail views on an enlarged scale, illustrating the successive steps in forming the openings or duets and the slots in lthe ring.

Fig, 5, is a vertical section of a cage embodying my invention, on a reduced scale.

Referring tothe drawings', 1 represents the tube or sleeve of the cage'and 2 a ring whose external periphery fits tightly the interior of `said tube Vfor sleeve `1. The interior space 3 of the ring 2 is shaped to receive the cake to be pressed-`in the drawings a cage embodying my invention,

the interior is nearly square to receive simil y e larly shaped' cakes.

Around all interior edges of the ring and at or near said perimeter, the ring 2 is provided with as eries of openings, 4, through the ring. Each opening or duct communicates with the interior 5 .by machine operations1 the slots are both too long and too wide. It becomes necessary therefore to shorten the slots and to bring their walls so close together atthe e11-V trance that a minute passageway will be formed to permit oil 'only to flow from the interior of the ring'and cageto the ducts 4.v

Thel preferred manner of accomplishing this resultis as follows: f f

Afterthe ducts4 are formed and the slots 5 cut through the ring (see F ig. 2), the ducts 4 are broached to substantially pear shape (see Fig. 3). This operation enlarges the duct substantially and shortens the length of the slot 5, but Without bringing the ivalls oi the Slot together` The edges of the slot 5 are then rolled or svvaged down as at 6 (see F ig. Ll) and a narrow opening is thereby formed, the slots being so closed and shortened that only oil can pass from the interior oi' the cage through the shori passageway which expands into a vertical duct 4L. j

The cage is formed by forcing a multiplicity of rings or frames, 2, after the formation of the ducts and slots, therein, into a sleeve l into which they tightly fit, With the ducts in each ring registering with the ducts in adjacent rings. When the sleeve is iilled, the result is a unitary cage, made up of multiple rings held in true position by the frictional engagement of the peripheries of therings with the inner surface of the sleeve l.

vHaving thus described the nature and object ot my said invention, what l claim as new is 1. lin a cage ior oil presses, a multiplicity of rings, each formed to receive a cake of material to be pressed, each ring having a series ci ducts therethrough from face to face and a series of corresponding slots lengthwise of the duct extending from the interior perimeter of the ring to the duct; means to hold the assembled rings in true relation and to forni a cage. y

2. in a cage for oil presses, a sleeve; one or more rings each having an external periphery closely fitting the interior of the sleeve and each having an interior space to receive a calie to be pressed, each ring having a series oi? ducts extending through the ring from face to face and a series of slots, each extending from a chiot through the internal perimeter oi' a ring.

3. ln a cage for' oilpresses, a sleeve, one or more rings, each having an external periphery clcsely litting the interior of the sleeve and each having an interior space to receive a cake to be pressed, each ring having a series of ducts extending therethrough from face to tace and a series of slots, each extending from a duct through the internal perimeter oi the ring, said ducts being breached to diminish thelength of the slots,

and the interior of the ring being rolled down along the inner edges of the slots to narroiv the slots to minute dimensions.

in a cage for oil presses, the combination or' a multiplicity of rings, each formed to receive a cake of material to be pressed,

each ring having a series of `ducts there-v through from face to'face, each duct regis tering Wit-li a duct iii the ring adjacent and having also aseries of corresponding slots Vparallel with the ducts, each extending from the interior perimeter of the ring to the coi'- responding diict, said slots being of minute Width at the interior perimeter of the ring; a sleeve in which the rings are assembled to hold the rings in true relation and to form a cage.

5. A ring for the purpose described having its interior shaped to tit a formed oil cake and having a series of cucts adjacent to the interioiivall of the ring and extending `from face to face oi ,the ring and a series of slots formed in the interior Wall of the ring and each connecting a duct vith the interior of the ring, the. internal edges of each slot forming a minute opening from the iiiterio'r of the ring into the ducts.

6. A ring for the purpose described, having its interior shaped to lit an oil cake and having a series of ducts adjacent to the iiiternal perimeter of the ringaiid a series of slots formed in the interior Wall of the ring and each connect-ing a duct with the interior of the ring, each or' said ducts being shaped to diminish the length of said slotsand the edges or sides of each slot forming a minute opening Yfreni the interior of the ring into said ducts. Y v .Y

7. The method ofiforming rings for cages ifor presses, 1which consists in shaping it to tit respectively the .ring-supporting means and the calze to be pressed,rtlien forming a plurality ciE openings or ducts in the-ring frein tace to face of the ring `and adjacent to the internal perimeter of said ring, next forming slots in the Wall of the interior space or' the ring,.said slots extending from the ducts to the interior of .the ring, and finally distorting `the edges of each slot to narrow the entrance of the slot.

Y 8. The inethod'oi forming rings for cages fcrjpressea'which consists in, shaping Vit to lit respectively the ring-supporting means.
